Study of Dengue Virus Transovarial Transmission in spp. in Ternate City Using Streptavidin-Biotin-Peroxidase Complex Immunohistochemistry.

is the most dominant vector in the transmission of dengue hemorrhagic fever (DHF). In addition to , is a secondary vector of the dengue virus, and both species are widespread in Indonesia. The dengue virus is transmitted from person to person through the bite of an spp. The vertical (transovarial) transmission of the dengue virus from infective female mosquitoes to their offspring is one of the means by which the dengue virus maintains its existence in nature. Transovarial dengue virus transmission in spp. mosquitoes contributes to the spread and maintenance of the dengue epidemic. This study employed a qualitative survey to detect dengue virus transovarial transmission in Ternate using the streptavidin-biotin-peroxidase complex (ISBPC) immunohistochemical test. The ISBPC examination of samples collected from the four subdistricts in Ternate revealed a positive result for transovarial transmission of dengue virus. Four spp., including two females, one female, and one male, tested positive for transovarial transmission of dengue virus in the district of North Ternate. Four spp., including three females and one male, were found to be positive for the transovarial transmission of dengue virus in the Central Ternate district. Seven spp., including five females, one male, and one female, tested positive for transovarial transmission of the dengue virus in the district of South Ternate city. One male showed positive results for transovarial transmission of dengue virus in the Ternate Island District. In this study, the transovarial transmission of the dengue virus occurred in both spp. female and male mosquitoes. It was demonstrated that spp. carry the dengue virus in their ovaries and can pass it on to their offspring. As a result, the cycle of passing the dengue virus on to local mosquito populations in the city of Ternate is not going to end just yet.
